I have recently downloaded 2.0b9 and installed it.

When I attempt to add JavaScript mode it downloads the files but fails installation with the messages

Could not delete C:\Users\Peter\Documents\Processing\modes\mode9139477983085052463tmp\JavaScriptMode\keywords.txt
Could not delete C:\Users\Peter\Documents\Processing\modes\mode9139477983085052463tmp\JavaScriptMode\mode\JavaScriptMode.jar
Could not delete C:\Users\Peter\Documents\Processing\modes\mode9139477983085052463tmp\JavaScriptMode\mode
Could not delete C:\Users\Peter\Documents\Processing\modes\mode9139477983085052463tmp\JavaScriptMode
Could not delete C:\Users\Peter\Documents\Processing\modes\mode9139477983085052463tmp

Which is strange because it attempts to delete the temporary folder and contents before copying them into the Processing/modes folder.

If I copy the files manually JavaScriptMode appears in the IDE but when I attempt to change to this mode I get exception message shown below. It appears that it can't find some images.

I have found nothing in the issues list so I image it is not a problem with Processing. Has anyone else experienced the same problem or know of a solution?

FYI - my OS is WIndows 7 Professional (64 bit)
